1. This large centrifugal fan was designed and constructed by FBA for use in a dust extraction system in a South Australian Foundry. Aerofoil type blades were adapted for maximum efficiency, with the fan producing air volume of 20,000 l/s and static pressure of 9 kPa. An auxiliary shaft was directly coupled to the main fan shaft, to enable the use of standard grease lubricated bearings, while transmitting the power of the 265 kW motor through a belt drive. This was typical of the ten fans supplied.

2. This two stage blower was designed and manufactured by FBA for an international ship builder in Freemantle, WA. The fan was used to bubble air along the catamaran hulls. The impellers were manufactured from 316 stainless steel, casings and the base from marine grade aluminium. The fan was selected to produce air volume of 4,000 l/s and static pressure of 20 kPa. The power available limited the maximum motor size to 75kW, which placed considerable importance on fan efficiency.

3. The high-pressure blower pictured, was designed and manufactured by FBA for the manganese industry. The client required a highly efficient, self-cleaning fan that could also operate within stringent power requirements. The FBA team designed, developed and supervised the entire process, which culminated in the production of an extremely large high-pressure blower, with an impeller that measured 1500mm in diameter. The fan was constructed of 2304 stainless steel.

4. This very large centrifugal fan, a Size FBA 80 DWDI, 2.05 metre diameter impeller with aerofoil blades, designed to produce 63000 l/s, was constructed by Fan & Blower Co for use as a carpark exhaust fan at the new Parramatta Police Station NSW.

The overall height of the fan when completely assembled was 3.75 metres. The maximum space available to allow entry to the building was 3.4 metres. To enable the fan to pass through this space the fan was constructed with a horizontal split case, this enabled the top section to be removed to allow the fan to fit through the restricted height limitation. Also, the casing sits in the base, not on top of the base, allowing extra valuable space to be saved.
